小型水产加工企业废水处理工艺改造

Modification of the wastewater treatment process of a small-scale aquatic products processing enterprise

某水产加工公司原废水处理系统已不能满足环保要求,根据水产加工行业废水的特点,在原有传统处理工艺的基础上进行了工艺改造,增加了絮凝反应池和MBR池,改造了好氧池,大大改善了出水水质,使排放废水达到《污水综合排放标准》(GB 8978—1996)一级排放标准要求。

The original wastewater treatment system of an aquatic product processing company could not satisfy the requirements of environmental protection. According to the characteristics of aquatic product processing wastewater, and based on the original ＆ traditional treatment processes,technical modifications have been carried out,for example, increasing flocculation reaction pool and MBR pool, and renovating the aeration pool. The results show that the effluent water quality is greatly improved, meeting the requirements of the first class of Integrated Wastewater Discharge Standard （GB 8978-- 1996）.
